Algebra and Combinatorics Trail Mix  

Instructor: Nicole Shen

In this course, we will go over some common techniques used on mid AMC- to early AIME-level problems. Students will become familiar with methods and tricks that cover a variety of topics, especially in combinatorics and algebra. Topics include bijections, algebraic manipulation, using inequalities, sequences and series, and recursions.

Schedule

LESSON 1: Counting Clever Correspondences

LESSON 2: Algebraic Manipulation

LESSON 3: Inequalities

LESSON 4: ∑equences and ∑eries

LESSON 5: Recursion and States

LESSON 6: Look to the Future

Counting and Probability Principles  

Instructor: Sanjana Das

In this course, we cover common methods in counting and their applications, on early to mid AIME-level problems. Topics will include constructive and complementary counting, PIE and constructing sets, bijections (such as Stars and Bars), recursion, and path-counting.

My Favorite Things  

Instructor: Isabella Quan

Vieta, trig functions and prime number theories ♪
Mass points, right triangles and coordinate bashing ♩
Manipulation and geometric series ♬
These are a few of my favorite things~

In this class, we’ll be talking about a variety of tricks that are prevalent on the AMCs and early to mid AIME which I find to be particularly elegant or beautiful.
